Introduction
|
||
|
|
============
|
||
|
|
|
||
|
|
HP EliteBook Folio 9470m is a 14" ultrabook with a backlit keyboard.
|
||
|
|
|
||
|
|
Libreboot has support for this, in the Git repository and release versions
|
||
|
|
after (but *not* including the Libreboot 20230413 release.
|
||
|
|
|
||
|
|
Installation of Libreboot
|
||
|
|
=========================
|
||
|
|
|
||
|
|
You must first compile the Libreboot ROM
|
||
|
|
|
||
|
|
./build boot roms hp9470m_16mb
|
||
|
|
|
||
|
|
More information about building ROM images can be found in
|
||
|
|
the [build guide](../build).
|
||
|
|
|
||
|
|
This is an *Ivybridge* board which means that a neutered ME image is required
|
||
|
|
if you wish to flash the ME region. Libreboot's build system automatically
|
||
|
|
downloads, neuters (using `me_cleaner`) and inserts this if compiling from
|
||
|
|
source.
|
||
|
|
|
||
|
|
If you're using *Libreboot release* ROM images, the ME image has been scrubbed
|
||
|
|
and you must re-insert it. Use the information on this guide to know how
|
||
|
|
to do that:
|
||
|
|
[Insert binary blobs on Intel Sandybridge/Ivybridge/Haswell
|
||
|
|
platforms](../install/ivy_has_common.md)
|
||
|
|
|
||
|
|
You may also wish to change the *default MAC address* if you're planning to
|
||
|
|
use the onboard Intel Gigabit Ethernet. You can do this using the information
|
||
|
|
in the same guide linked above, or read the nvmutil manual:
|
||
|
|
|
||
|
|
[Modify MAC addresses with nvmutil](../install/nvmutil.md).
|
||
|
|
|
||
|
|
Disassembly
|
||
|
|
-----------
|
||
|
|
|
||
|
|
Remove the battery.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Open the two screws marked with the three-disc icons.
|
||
|
|
Slide the HDD panel out and remove it.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
The flash chip is now comfortably accessible. Now refer to the
|
||
|
|
[external programming guide](../install/spi.html) for guidance on how
|
||
|
|
to program Libreboot on it.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
Some part of the board might turn on when programming. If programming fails,
|
||
|
|
you might have to attach the laptop to a charger. Make sure the laptop
|
||
|
|
powers off before running flashrom. No LEDs should be lit.
